Component list:
Skyworks 77352-15 GSM/GPRS/EDGE power amplifier module
SWUA 147 228 is an RF antenna switch module
Triquint 666083-1229 WCDMA / HSUPA power amplifier / duplexer module for the UMTS band
Avago AFEM-7813 dual-band LTE B1/B3 PA+FBAR duplexer module
Skyworks 77491-158 CDMA power amplifier module
Avago A5613 ACPM-5613 LTE band 13 power amplifier
Qualcomm PM8018 RF power management IC
Hynix H2JTDG2MBR 128 Gb (16 GB) NAND flash
Apple 338S1131 dialog power management IC*
Apple 338S1117 Elpida memory MCP for LTE*
STMicroelectronics L3G4200D (AGD5/2235/G8SBI ) low-power three-axis gyroscope—same as seen in the iPhone 4S, iPad 2, and other leading smart phones
Murata 339S0171 Wi-Fi module
STMicroelectronics LIS331DLH (2233/DSH/GFGHA) ultra low-power, high performance, three-axis linear accelerometer
Texas Instruments 27C245I touch screen SoC
Broadcom BCM5976 touchscreen controller
Rather than a single touchscreen controller, Apple went with a multi-chip solution to handle the larger screen size, à la iPad.
Apple A6 Application processor
Qualcomm MDM9615M LTE modem
RTR8600 Multi-band/mode RF transceiver, the same one found in the Samsung Galaxy S III
